<p>PROBLEM TO BE SOLVED: To provide a toner that is provided with hot offset resistance remarkably superior to the prior art in addition to low-temperature fixability.SOLUTION: There is provided a toner that contains an amorphous polyester resin and crystalline polyester, where in an endothermic curve at the temperature rise of the toner measured by a differential scanning calorimetry device (DSC), the endothermic amountΔH derived from the crystalline polyester is 1.0 J/g or more and 5.0 J/g or less; on the cross section of the toner observed by transmission electron microscope (TEM), crystals of the crystalline polyester observed in a needle-like shape are dispersed; in a number distribution of the length of the major axis of the crystals, there are 30 number% or more of the cross sections of the crystal having a length of the major axis of 100 nm or more and 250 nm or less.</p> |
